DUMPlNG-BOX FOR WAGONS.

SPEGIFIGATION forming part of Letters Patent N 0. 671,102, dated April 2, 1901.

Application filed July 11,1900.

To all, whom it may concern:

Be it known that 1, 'WILLIAM J. BLACK, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in VVagon-Boxes and the Like; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in wagon-boxes and the like of that class in which means areprovided for dumping the contents through the bottom of the box.

The invention consists of the matters hereinafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure l is a side elevation of a wagon-box embodying my invention. Fig. 2 is a view similar to Fig. l and showing the parts in the dumping position. Fig. 3 is a longitudinal vertical section of the same. Fig. 4 is a side elevation of a wagon-box embodying my invention and illustrating another form of the supporting device. Fig. 5 is a top plan view. Fig. 6 is a front end elevation. Fig. 7 is a central cross-sectional view.

As shown in the said drawings, A and A indicate the sides of the wagon-box.

Ct d are vertical end-boards extending from the top, near each end of the box, downwardly for a part of the depth of the same.

a a are sections of the end-boards, which join with the lower end of the vertical portions and incline centrally, as indicated in Fig. 3. V

B indicates a central shaft, herein shown as a piece of tubing of sufficient length to reach from over one of the hounds of a wagon to a point over the other and having a bearing at each end on the cross-pieces O G',which rest upon said hounds when the box is in position. The bottom of said box consists of two similar leaves or doors A A each hinged on said shaft or tube B and adapted to swing downwardly thereon to the position indicated in Figs. 2 and 7 when the load is dumped. As shown, said leaves or doors are each pro vided with three hinges,consisting of a strap Serial No 23,175; (No model.)

or bar of iron or other suitable metal extending across said door or leaf, as indicated in Fig. 5 by b b b for the door or leaf A and by b b b for the leaf A Obviously said hinges may be constructed of a single bar of iron provided with a suitable eye to receive said tube and extending across one of said leaves, or the same may be constructed as shown in Fig. 5, in which, as indicated, astrap of metal is bent around the said shaft 13, one end of the same extending transversely across the lower side of the door and the other end extending across the upper side of the said door and the two ends thereof bolted together through and through. The straps b or, in other words, those forming the central hinge for each door or leaf, extend outwardly beyond the sides of the box and are each provided with a hook or link b b", respectively, which afford means for supporting said doors or leaves in their closed positions.

D D are herein shown as ropes; but obviously the same may be chains or other flexible connections, one end of which is secured, respectively, to the hooks or links I) U, the other end of which leads upwardly over a roller or pulleys E or E and forwardly to levers F F, respectively, which are pivoted at their lower ends one on each side of the box and are adapted to be swung forwardly to a horizontal position, as indicated in Figs. 1 and 4, with the effect of closing said doors and holding the same supported in their closed position. Said rollers E E, located centrally and one on each side of the box, are pivoted upon bolts 8, the inner ends of which are secured to the sides of the box, the outer ends of which are supported in brackets of any suitable form, (herein indicated by e.) Said bracket, as shown, consistsof a downwardly and a rearwardly directed arm, each adapted to be secured at the side of the box, and a central plate integral with said arm adapted to engage the outer end of said bolt and form a bearing therefor. Means are provided for securing said levers F and F, respectively, in their locking positions, with said doors or leaves closed, which, as shown in Figs. 1, 2, 5, and 6, comprises a spring-catch ff, secured one on each side of the box in position to engage the forwardly-directed end of the lever when in its horizontal or locked contact with the supporting-lever.

said levers.

position. As shown, said spring-catches are leaf-springs, secured at one end at the top of the box and provided at the lower ends with a shoulder adapted to engage the power end of the lever when the same is in the position it assumes when supporting the doors in a closed position, as shown in Figs. 1 and 5. A rod f f is secured on each side of the box, which, with the cleats G G, serve as guides for said levers, confining the movement of the same to a plane parallel to the box sides. Means are provided releasing said levers from said spring-catches by motion of the foot, as follows: Inwardly-directed foot-levers H H, respectively, are provided at the end of the box in front of the end-board and in position ing the free ends of the springs ff, respec' tively, and acting when the free end of the lever is depressed to pull said spring out of A pulley or roller is provided on the pivot, whereby thelever is secured to the box side and between the same and the box, and a rigid rod or bar is secured at one end to said lever intermediate of its ends, and at the other end is secured the forwardly-directed end of a flexible connection or rope supporting the door or leaf, as shown in Figs. 1, 2, 5, and 6.

The operation of this device is as follows: When the levers are thrown forwardly in the position indicated in Figs. 1, 5, and 6, the leaves or doors A A are drawn upwardly int-o engagement with the sides of the box, thereby effectually closing the bottom of the same. The rod or bar d d engages the roller at the end of they lever, and the forwardly-directed end of the lever being lower than said pivot the tendency is for the rear end of said bar to be directed upwardly, as shown in Fig. 1, whereby the said bar or rod and the rope B are thrown out of alinement, with the effect of producing a constant upward strain on the The springs ff, however, hold the leversin their locking position. To dump the load, the foot-levers H and H, respectively, or either of them,may be pressed downwardly, according to whether it is desired to dump from both sides of the load at the same time or from one only. When said trip-letion shown in said figure, whereupon the contents of the box are permitted to escape therefrom. Obviously any form of locking device may be used to hold said lever in its forwardlydirected position, and the same, as shown in Fig. 4:, may be constructed in such a manner that the draft of the load on said lever will act to hold the same in such position. In this form of my invention the lever F pivoted, as before described, on the side of the box, similarly to the lever F, heretofore described, has secured thereto, intermediate of its ends, one end of the rope or band D or D, and a stop f is located on said box in position to engage thelower side of the leverand at a point lower than said pivot, so that as said lever is thrown forwardly toits lifting position the connection or rope D or D will extend below said pivot, with the effect of producing a constant downward strain on the lever.

I claim as my invention 1. In a device of the class described in com bination with side walls and inwardly-hr clined end Walls, of a longitudinal central shaft and having a bearing at each end on transverse members adapted to be supported on the bolsters of a running-gear, laterallydirected leaves or doors hinged on said shaft and adapted to form the bottom of the box and means for holding said-doors in their closed positions comprising a roller pivoted on each side of the box-and a connection of flexible material having one end secured to the free edge of a door having its upper end led upwardly and forwardly over said roller and secured to a lever also pivoted on the box and a spring-catch adapted to engage the free end of said lever when said doors are in their closed positions.

2. In a wagon-box, the combination with the side and end walls of laterally-directed leaves or doors forming a bottom, a rope secured to the free edges of said leaves or doors, a roller located above the point of attachment of said rope therewith and over which the same is led, a lever pivoted at one end on the sides of the box and a rod having one end secured to the end of said rope and having the other end secured intermediate of the ends of said lever and which bears over the pivot thereof when said levers support the doors in their closed position and a spring-catch engaging the power end of the lever and acting to retain the same in its supporting position.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

WILLIAM J. BLACK.
